To sign environment, stick up your non-dominant hand's index finger, then form an ASL letter E sign with your dominant hand and encircle your index finger with it.
Alternatively, you can form a flat number 5 sign with your dominant hand and encircle your index finger with it.
It is never too early to teach our toddlers to care for their environment. If they are big enough to want to help around the house by tidying up, making their bed, or simply throwing trash in the bin, then you can teach them the environment sign. Show your toddler how your neighborhood or community is enlisting the help of families, along with the kids, in keeping your streets and parks clean, by recycling, upcycling, or preserving nature and protecting the plant and animal life in the area.
Teach your child this sign along with other signs pointing to nature, geography, and plant and animal life.
